β¦ Synopsis
Different batches of agarose may lead to migration differences in the demonstration of C 3 polymomphism in high-voltage gel electrophoresis. We studied a particular batch (i.e. AGS 082) which caused two basic phenomena concerning mobility and electrophoretic position of C 3 phenotypes: I. C 3 variants migrate to the cathode, apparently due to a positive net charge of the protein caused by this agarose batch. 2. The relative mobility of slow and fast bands is virtually reversed.
Previously obtained results are controlled and verified by further investigations on rare C 3 variants. The possible causes of the net charge differences of the C 3 proteins in various agarose batches are discussed.
Zusozr~enfassung: Verschiedene Agarose-Chargen k~nnen zu einer uneinheitlichen Darstellung des C3-Polymorphismus in der Hochspannungs-Gelelektrophorese fNhren.
Speziell die Behring-Agarose AGS 082 bewirkt hinsichtlich der Mobilit~t und Elektrophoresemuster der C3-Phgnotypen zwei grundlegende PhNnomene: I. C3-Varianten wandern kathodisch, offensichtlich eine Folge der positiven Aufladung des Proteins, die durch diese Agarose-Charge bewirkt wird. 2. Die Umkehrung der relativen Mobilitgt der langsamen und schnellen Bande.
Vorausgegangene Ergebnisse werden anband weiterer Untersuchungen se]tener C3-Varianten Oberprgft und bestNtigt.
Die mSglichen Ursachen fHr diese Agarose bedingten Ladungsdifferenzen der C3-Proteine werden diskutiert.
